Floribunda rose plant named `Jacquint`

ABSTRACT

Floribunda rose plant having large flowers of strong fragrance, vigorous growth, compact plant habit and disease resistant foliage.

The present invention relates to a new and distinct variety of rose plant of the floribunda class which was originated by me by crossing `JACdew` (U.S. Plant Pat. No. 5,122), with `HARrooney` (U.S. Plant Pat. No. 5,582).

The primary objective of this breeding was to produce a new rose variety having the vigorous growth, disease resistant foliage and abundant flowers of the female parent combined with the fragrance, compact growth and large individual flowers of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Strong fragrance;

2. Vigorous growth;

3. Disease resistant foliage;

4. Large flowers;

5. Compact plant habit.

Asexual reproduction of this new variety by budding, as performed at Wasco, Calif., shows that the foregoing and all other charactertistics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.
